The 10 Most Incredible Hackers In History

10. The Morris Worm

The Arpanet was the precursor to today’s Internet. It was just beginning in the late 1980s, when a young man by the name of Robert Tappan Morris unleashed the first worm virus. The worm virus is able to hide itself on a computer’s hard drive, replicate itself, and spread to other computers on its network. So when it was released on November 2, 1988, by Morris it was intended to be harmless.
